The CD Projekt Red did not secret that Witcher 4 would not be with us soon. The last word we have heard about this problem is that it will not be released faster than 2027. It's not surprising given that the public trailer is purely cinematic.
So it's amazing when we get something that looks like a gameplay trailer in the state of the realized showcase. Then CD PROJEKT Red says it's a technical demo, so this is more eager than demonstrating what we'll play. Now developers have shed light on what this means and the goals they want to create.
The Witcher 4 Devs explains what the technical demo of the final game means.
In conversation with Digital Foundry, many developers from CDPR and EPIC Games answered some questions about the development of technical demos and the development of The Witcher 4. Here they ask about the consistent 60fps experienced when the digital foundry has tested the demo itself.
Charles Tremblay, the vice president of Technology of CDPR, said, “At this stage we are still doing a lot of effort ahead of us.” This is a technical demonstration. […] There are no battles and many things [don’t] It's work, but still ambitions are set.
“This is a place we want to do, and we will be cursed if we don't try to get this game from the performance.” “It's too early to say if we can nail it, but we will work as hard as possible to make it.”

Is it too good for Witcher 4 to run on PS5 to 60fps?
The CD Projekt Red best looked at Witcher 4 in this unrealistic presentation this week.
Therefore, we need to make sure that the waiting Witcher 4 will be smoothly smooth as in the demo. When it is released, it will probably be the end of the PS5 and Xbox Series X/S Life Cycles. This is because the subsequent may come out until then. The game of this caliber will still be a great feat.
